Abstract Purpose: Avoiding supine position can reduce snoring in most habitual snorers. However, devices that restrict the sleeping position cause discomfort or disrupt sleep resulting in low compliance. Therefore, mechanisms, which lift the trunk of the user without disturbing sleep, have been proposed. We present the first study, which investigates whether individual interventions provided by beds with lifting mechanisms are able to stop snoring (success rate) and whether they reduce the snoring index (number of total snores divided by total time in bed) using a repeated measures design. In addition, we investigated whether the intervention is interfering with the subjective sleep quality. Methods: Twenty-two subjects were observed for four nights (adaptation, baseline, and two intervention nights). During intervention nights, the bed lifted the trunk of the user in closed-loop manner. Subjects were divided in three groups (non-snorer, snorer one, and snorer two). Non-snorers were lifted by the bed at random time points during the night. In group snorer one, a stepwise increase of the bed inclination was compared with going directly to a randomly selected angle. In group snorer two, the influence of a small inclination angle (10°) and a big inclination angle (20°) was compared. Results: Snoring was stopped successfully in 22% (small angle) and 67% (big angle) of the interventions. This did not lead to a significant reduction in the snoring index. The subjective sleep quality was not reduced by the intervention. Conclusion: The anti-snoring bed is able to stop individual episodes of habitual snoring without reducing the subjective sleep quality. Trial Registration: https://clinicaltrials.gov, no.

Introduction Habitual snoring is a widespread sleep problem (Deary et al. 2014), which does not only affect the health of the snorer (Endeshaw et al. 2013) but also the quality of life of the bed partner (Beninati et al. 1999). Intense snorers snore up to 245 times/hour (Cathcart et al. 2010). Snoring often occurs when the muscle tone drops while the snorer is lying in supine position. In this position, gravitational forces pull the soft tissue surrounding the upper airways in dorsal direction, thereby narrowing the *Correspondence: [email protected] Sensory-Motor Systems Lab, Department of Health Sciences and Technology, Eidgenossische Technische Hochschule Zurich, Zurich, Switzerland Full list of author information is available at the end of the article 1
airways. This causes audible flow turbulences in the upper airways (Gleadhill et al. 1991). Therapeutic interventions force snorers to avoid supine position. The easiest way to implement
